BOOK COVER,

Application filed October 11, 1924. Serial No, 742,984.

To aZZwwm t may concern:

Be it known that I, JOHN SCHADE, a citi- Zen of the United States, residing at Holyoke, county of Hampden, and State of Massachusetts, have invented certain new and useful Improvements in Book Covers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to book covers of the style and general construction exemplified in my pending application, Serial No. 654,300. l

In said application the metal back andthe side covers were equipped at their edges with complementary hinge eyes which were interengaged and then secured in hinging relation by means of a pintle inserted through the eyes, but in the present improvement, the metal back and the covers are provided with elements that are directly interlocked so as to effect a direct hinging with Vno pintle whatsoever or anything else intervening.

The object of this invention is to provide a book cover, similar in appearance to that shown in said application, but in which the' hinging is effected by interlocking elements and not by elements that are interengaged and then secured by a pintle. In other words, my present structure does away with a pintle device since there are only two elements, one carried by the metal back and the other carried by the covers, that effect the hinging.

In the acompanying drawings- Figure l is an inside view of one form of my book cover with the covers in 'open position.

Figure 2 is a similar View of another form of my invention.

Figure 3 is a section at the line 3-3 of Figure l.

Figure 4 is a section at the line 4 4 of Figure 2. y

Figures 5 and 6 are fragmentary outside elevations of the structures shown at Figures 1 and 2 respectively.

Figures 7 and 8 are detail plans of the metal strips that are secured to the covers in the constructions shown at Figures 1 and 2 respectively, and

yFigure 9 is a detail view ,of a1 4metal back showing a modified form of opening therein.

Similar numerals of reference denote like parts in the several figures of the drawing.

Referring to Figures l, 3 and 5, 1 is the metal back having at its side edges spaced openings 2. 3 are the covers having secured to their inner edges in any suitable manner metal strips 4 from which project spacedy fingers 5.

In assembling the book cover, these fingers are inserted through the openings 2 and curled around, thus neatly hinging the covers to the back. In other words, one hinge element, the fingers, is interlocked with the other set of hinge elements, the openings, and then curled around.

In the construction shown at Figures 2, 4, and 6, spaced openings 6 are formed in projection 7 integral with the metal strips 4 that are secured to thecovers, and spaced fingers 8 extend from the side edges of the metal back, and in assembling, these ingers are inserted through said openings and curled around just as in the structure shown at Figure l, so that it will be obvious that there is no material difference between the book covers shown at Figures 1 and 2.

In order to give a more pleasing effect and a neater finish to the book cover shown at Figure 2, the projection 7 is slightly bent as shown. In the constructions shown at Figures l and 2 the openings consist of holes formed in the back plate or the projection, but the style ofopening is immaterial, and at Figure 9 I have shown openings 9 that lend themselves to my invention equally as well as the openings shown in Figures l and 2, and I therefore do not wish4 to be limited in this respect.

While it is preferred to make the back portion of metal, it is, of course, within the province of this invention to make this back of hard pressed cardboard, or stiffleather,

with the holes cut therein to receive the'ing j i 1,557,883

edges of the metal back might be provided spaced openings, elongated metal strips from either with holes or with the projecting fin- Whose opposite side edges project spaced 15 gers, according as the construction is of the fingers and clinching members in staggered style shown at Figures l or 2 respectively. relation, said members being driven through 5 since these possible changes are mere the inner marginal edges or" said covers and mechanical variations of my preferred strncthen clinched thereto, While said lingers are ture and do notifise to the dignity of modi-i inserted through said openings in the back 20 cations, it is not deemed necessary to illusand curled around to form` hinge connectrate them. tions.
